Had the Bonneville out tonight, first time in a week, it was warmed right up, took it onto the highway, slowly accelerated TC no longer locks at 48 it locks at 54...last week it would go in at 48....i tried this about 10 time at any throttle it will not go in until 54 on the HUD

mine will lock occasionally at 48...or not until about 52 or so...depends on hils and load and **** like that I believe.

Flat surface, any surface..last few times i had it go in at 48 it shudderd badly.

it depends on the engine load, and throttle angle, but locking at 54 is not normal.....

wail till Jr comes in here....

dang, so much for the flush doin you some good :( . hang in there, you'll get you one of them shiny new trannies.

Matt..knowing you arre having transmission troubles I wouldn't doubt that the more you drive the car the worse the transmission will act.

It'* only a matter of time and how quickly things break down as to how soon you notice more problems.

Under no load condition mine comes in at about 45-46mph right after 4th gear.

I came across that crappy fluid in my garage tonight, poured it out, here is what was in the bottom of the pale..bare in mind, most of the grey crap poured out too, this is what i could reserve for a picture.

Tranny fluid and residue

yukky clutch material! Anyone know if the flush i had done would of removed the material from the bottom of the pan or if i should drop the pan and wipe it all out.?
